The atomic mass of an element is a weighted average of all the element’s isotopes based on their natural abundance. It is simple to calculate the atomic mass of an element with these steps. Web4 jan. 2024 · Newton. The first to calculate (or, estimate) the mass of the moon was probably Newton himself. As mentioned by Baso, Newton used measurements of tides to find the ratio of the lunar and solar masses. This is realised through the tidal force equation: f S = 2 G M S M E R E 3, f M = 2 G M M M E R E 3. Where we take the absolute value. inconsistency\\u0027s vu
